Abstract
A wireless target activation system for a train, the system including at least one computer programmed or configured to: receive at least one first target location and at least one second target location associated with a forward route of the train, wherein the at least one first target location is located before the at least one second target location on the forward route of the train; determine a gap time between when the leading edge of the train leaves the at least one first target location and is estimated to arrive at the at least one second target location based at least partially on a distance between the at least one first target location and the at least one second target location and a design speed; and based at least partially on the gap time, an allowable acceleration of the train, and a required warning time, generate an activation message configured to activate or cause the activation of at least one function associated with the at least one second target location.
